Which of the following is an acceptable method of protection for service-entrance cables if likely to be physically damaged?

Service-entrance cables are essential for supplying electrical power to a building, and ensuring their protection from physical damage is crucial for safety and functionality. The correct answer encompasses both acceptable methods of protection: using conduit and installing a protective cover.

Using conduit provides a robust physical barrier around the service-entrance cables, helping to shield them from impact, abrasion, and environmental factors that could cause wear and tear. Conduit materials, such as metal or PVC, are designed to withstand external damage, making them an ideal choice for areas prone to physical forces.

Installing a protective cover also serves to guard against potential hazards. A protective cover can be designed to resist impact and environmental influences, offering another level of safeguarding for the cables. This method is often used in locations where cables may be exposed to incidental contact or environmental stresses.

By utilizing one or both of these methods, electrical contractors can ensure that service-entrance cables are adequately protected against physical damage, thereby enhancing the safety and longevity of the electrical system. Therefore, recognizing both options underlines the flexibility of protection strategies that can be implemented based on specific conditions at the installation site.
